"Simple DM tip: take monsters you usually use a simple combat threats and write a couple three up as NPCs with names, backstories, motivations, etc. Doesn't matter if they don't normally talk. Sylvia the Owlbear and Joey Greenslime may be the new hit characters of your game."I was instantly reminded of how funny it was when I gave a group of mushrooms names, goals, and families in a whimsical adventure that had the players journey through enchanted forests — shrunk all the way down to the size of tiny pixies and snails — and reunite with the tiny button child of one of the mushrooms they crushed underfoot right off the bat who became a great mushroom hero, renowned all throughout the grove. So, for today, I present a handful of not-so-normal NPCs that can make for interesting moments in, I think, any role-playing game out there.

Ursula, Sky-Terror. Giant Cardinal.
Ursula's life was quite quaint. Flying with Ursula's companion, diving at insects, watching the bees buzz and swarm and the great warrior birds hunt, dominating the skies. The only exciting moments were visiting Ursula's window-friend for precious treats, those moments were too short for Ursula.
Then, a few years ago, she was given an explosion of thought and drive and purpose by their window-friend — a young, very curious wizarding girl as it turns out — who also accidentally made Ursula grow to the be bigger than all but the biggest bears. A dream come true for Ursula, Queen of the Skies, Slayer of the Darkwood Spider-Fiends, and Guardian of The Island and the window-friend, Samantha, who gave even sweeter treats and wonderful head scratches every week in exchange for bird communication lessons.
Last week Samantha became sick, Ursula hasn't seen Samantha since and is worried.
Sadiron. Two-Headed Couatl.
They hate the color purple and wish to see it removed from the world, whenever they have the chance to destroy something purple they will try their best to do so. They love the god of the sun, sunrises, and the color orange more than anything else in the world and will never harm another creature who feels the same way. They are a long-standing member of the Dawnbreaker Alliance and always have an eye out for potential recruits and champions of the color orange.
Otis. Hell Hound.
Otis is a muscular, large white-haired hell hound. He wears a stone collar with infernal script that reads "domgrethal odd marus."
He cannot help himself from doing two things: howling at birds and rolling in tar pits. When their master is away and did not speak the command "domgrethal odd marus" before leaving, he will sleep to his hearts content and ignore all noise and commotion (as long as no birds or tar pits are in sight); otherwise, he will sit on guard until his master returns and pets him, fighting any creatures that come within 15 feet to the death who were not within 15 feet when his master spoke the command.
Regil. Camel.
His last partner was an old warmongering type who worked as a ratcatcher for a year but quit after not being able to catch any after the first (sheer dumb luck). He always knows the best place to hide and the best place to sleep. He knows a poorly made trap when he sees one and will do his best to let the maker know so they don't end up like the ratcatcher. He likes cats of all kind and size but is very allergic to them and knows it. What he doesn't know is that he is deathly allergic to citrus.
Regil knows the following spells, requiring no components to cast (can use 3/day, DC 11 saving throw): alarm, comprehend language, hold person, longstrider, power word stun.
Ban'thracc. Umber Hulk.
"Feed the whelps, he says. Bite harder, he says. Clean my scales faster, he says. Move the hoard, he says. Tunnel DEEPER, he says! It's time for Ban'thracc to get what he wants, I says. Well, the Demon says Ban'thracc should get what he wants, but Ban'thracc agrees..."
When Ban'thracc encounters strangers for the first time, he will run away in fear. If he encounters someone for the second time, he will try to communicate with them and convince them to kill the lord of the dungeon. If he is attacked or belittled by anyone other than the lord of the dungeon, Ban'thracc will become enraged and attack them.
It's always great to have simple concepts like this in your toolbag that, at the very least, add fun secrets to the game, but can also spark exciting, memorable moments for everyone at the table. Of course, a large part of the beauty of this (for me) is that any of these ideas can be used as templates and stuck onto just about any kind of creature: manticores, dragons, zombies, displacer beasts, perytons, giant beetles, brass minotaurs; even items like poor Della, or features of the environment like an oddly shaped rock formation or a pond turned into a sentient elemental. Hopefully someone out there was inspired as much as I was, thanks to @jrients for the idea.
And one last thing that I doubt will fit better anywhere else...
They were a tall, big, lovable mountain of a woman who knew everyone in the four villages: the smiths, cobblers, potters, the captain of the guard and his ten sons, the dockers and their children, every lumberjack and all of their mothers, the tailors (and their scowls and smirks when she would arrive in near threads), and all of the pie-makers and pork-smokers for a hundred miles or more. Along with her great grandmother's axe Jowena (named for the woman herself, rest her heart), she was the greatest woodcutter in six generations; since her great great great great grandfather Broxus the Bonesaw, that is.
On one peculiar, misty afternoon in the spring, *chock* ... *chock* ... *chock* landing the final blows on the final tree of the season, she watched a lanky creatures climb out of the trunk of another oak nearby. When she turned to see the reactions of her companions, only mist was to be seen. She could hear their shouts but only muted. *pop* She poked in her ears to clean them, surely it would help. It didn't help. Looking back and forth, up the slight hill, around the tree, nothing. Then the creature was right in front of her. They were tall, as tall as her, but had long floppy ears like coattails and impossibly fine, black hair and dangerously sly, bright blue eyes. And soft hands, the softest hands, and nimble. The complete opposite of her hard, rough paws. One of those hands felt hers and the other lifted her axe. Everything seemed to stop in that moment, she remembers it perfectly, every day, the moment when their eyes looked straight on into hers. Their face turned into a hideous scowl.
Everything after that is a series of blurs. They took the axe, at least she thinks, swung at her and they fought, and she remembers hearing someone else shouting in the thick mist. Then all of a sudden it was over. The mist cleared and she looked up from the ground next to the old oak, "only a minute more and it would have fallen" she remembers thinking. She saw the edge of Jowena glinting in the sun, the mist had cleared. She tried to get up but couldn't move her arms, and her feet were stuck in the ground.
In time, she would watch that old oak finally be felled by her younger cousin, now swinging her great grandmother's axe with the aim of a blind badger, but it was good enough. Other trees would fall, after what seemed like a lifetime there were only a few small trees left in the grove. It was mostly just her, the warm dirt, the cool grass, the beetles and birds, and a field of yellow and white flowers. And one beautiful blue flower. It reminded her of that man. *chock* That sickening sensation. A shallow sucker punch, but it burned deeper than any other fist blow or needle prick or broken bottle slice she had ever felt. The burning grew then became numb.
The trip there is lost from her mind along with most of her stay in the old woodmaker's shop. She wishes she could forget that entire moment in her life. Being stripped and butchered, feeling parts of herself get ripped away and cut down, then what was left of her getting pinned back together. After these many lifetimes it was still too vivid.
